Intraoral transposition of traumatic parotid duct fistula.

Parotid duct fistula is uncommon but difficult-to-treat complication that often results from a penetrating trauma. While there is general consensus in the literature as to the management of acute parotid injuries, treatment of chronic fistulas remains controversial. We review the current treatment options for parotid duct fistulas and describe an intraoral diversion technique to reestablish salivary flow in the setting of a nonfunctional parotid duct punctum.
